SPECIFICATION forming part of Letters Patent No. 536,352, dated March26, 1895.

Application filed-January 3 1 8 95 To all whom, it may concern:

Be it known that we, EDWARD C. J'UDD, of Boston, in the county ofSuffolk, and ABNER O. PAUL, of Lynn, in the county of Essex, 5 State ofMassachusetts, have invented certain new and useful Improvements inSole-Laying Machines, of which the following is a specification.

This invention relates to machines for apxo plying pressure to a solelaid upon the portions of the upper of a boot or shoe that project overthe bottom portion of the last, and maintaining such pressure while thecement which has been applied to the contacting surfaces of the sole andupper is setting or hardening, the object being to temporarily securethe sole to the upper preparatory to the permanent attachment of saidparts by stitches or other fastenings.

The invention has for its object to provide an improved construction ofthe platen or presserwhich bears upon the outer surface of the soleduring the pressing operation and co-operates with the jack whichsupports the lasted upper in securing the desired intimate contactbetween theinner surface of the sole and the upper.

The invention also has for its object to provide improved means in apower-operated 3o machine for bringing the upper and sole into contactwith each other before the power of the machine is applied to completethe pressure.

yTo these ends, the invention consists in the improvements which we willnow proceed to describe and claim. l

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a vertical central section of a machine em- 4obodyingourimprovements. Fig.2represents a section on the planeof line 22 of Fig. l,

and a plan view of portions of the mechanism below said line. Fig. 3representsA an elevation of a part 0f the jack-raising mechanism shownin Fig. 1. Fig. 4 represents a perspective view of a portion of thejack. Fig. 5

represents a sectionaly view of a portion of` the machine on alargerrscale than shown in Fig. l. Fig. 6 represents an enlargement of5o a portion of Fig. 5. Figs. 7 and 8 are diagrams showing thefoot-power actuated means Serial No. 533,767. (No model.) l A' forraising the jack into contact with the presser or platen. Fig. 9represents a sectional view showing a different construction of themeans for supporting the presser or platen.-

The same letters of reference indicate the same parts in all thefigures. y In the drawings, a represents the supporting standard orpedestal of the machine, upon 6o which is mounted to rotate horizontallya, frame carrying the sole-pressing and shoesupporting deviceshereinafter described, said frame comprising a vertical tubular portionb, a base portion b,and a top portion or head 65 b2. The rotary frame isprovided with a plurality of jacks which support the lasted uppers of aseries of boots or shoes, and with a plurality of sole pressers orplatens which co-operate with the jacksand the lasts thereon 7o inpressing the cement-coated soles against the cement-coated uppers; andas all the jacks and pressers or platens are alike, we will describe theconstruction and mode of operation of one jack, and the accompanyingpresser or platen.

The head b2 is provided with a springv pressed coupling or joint memberc, which'is movable vertically in a guide or socket b3 forming a part ofsaid head, and is pressed 8o downwardly by a spring c bearing at itsupper end on a shoulder in the socket b3 and at its lower end on thecoupling member c.- The under side of the coupling member is concave,and constitutes a seat upon which bears a coupling or joint member dformed on the `platen or presser, said coupling member d being convexand constituting with the coupling member c the equivalent of aball-andsocket joint which permits a free oscillating go movement of thesole-presser or platen not p only lengthwise but crosswise. 1n otherwords, the said presser or platen has a universal tip- Y infr motion. Y

The presser or platen is composed of a holder d upon which thecoupling-member CZ is formed, a sole-pressing pad d2, and a heelpressingpad d3 affixed respectively to rigid back-pieces d4 d5 which havedovetailribs d, by means of which they are detachably afroo fixed totheholder. The rib d6 of the heelpressing pad d3 is engaged with a dovetailgroove formed in the holder d', while the rib of the sole-pressing padis engaged with a dovetail groove formed in an arm C27 which isadjustably connected to the holder, in order that the sole pressing padmay be given various inclinations although at all times rigidlyconnected with the holder, said arm d? being pivoted at d to the holderand engaged at its outer end by a ball-andsocket joint with ascrew-threaded adjusting-rod al which works in a spherical nut d10contained in a socket d12 formed on the holder d. By rotating said rodd, the outer end of the solepressing pad cl2 may be raised or lowered,as the ease may be, and said pad thus adjusted to the curvature of thetoe portion of the last, the toe being higher in some lasts than inothers. Vile do not limit ourselves to the employment of an adjustablesole-pressing pad, however, and may attach the said pad to the holder inthe same manner that the heelpressing pad d3 is attached, the two padsbeing in all cases rigidly attached to the holder and incapable ofindependent yieldingr or selfadjusting movement excepting such movementas may be due to the elasticity of the pads themselves, the latter beingpreferably comparatively thick blocks or pieces ot' rubber fixed to thebacks d4 d5.

It will be seen that the spring c exerts a downward yielding pressureupon the coupling-member c, and through the latter upon the presser orplaten, the latter being therefore adapted to yield bodily to thepressure exerted against it by the jack, as hereinafter described, thisyielding movement of the presser or platen enabling it to conform to thethickness of the sole and the size ot' the last interposed between itand the jack.

To limit the yielding movement imparted to the presser or platen bythespring c', We provide a stop e, which, in the construction shown inFigs. l and 5 is a collar having a` convex upper surface tting theconcave under side of the coupling-member d. Said collar e is providedwith a tubular stem or shank e,which extends upwardly through the socketb3 and constitutes aconnection between the stop e and the head b2 whichrigidly supports the stop and causes it to support the presser or platenagainst the downward pressure of the spring c', said stop permitting theyielding movement of the presser or platen. We prefer to make theconnection between the stop and the supporting-frame adjustable, so thatthe stop may be depressed `or raised to Vary the initial position of thepresser or platen from which its yielding movement commences. To thisend, we have shown in Figs. l, 5,and 6, an internally screwthreaded nutor bushing e2 fitted to rotate in a socket formed in the head b2 andengaged with an external thread formed on the tubular stem e', saidbushing c2 being provided with a hand-wheel e8 by which it may berotated to raise or depress the tubular stem c and stop c. YVhen thesaid stem and stop are depressed, the spring c forces the presser orplaten downward, so that its normal position is lower than before; andwhen the stop is raised, it raises the presser or platen with it, thespring c' yielding, so that the normal position of the presser or platenis higher than before.

The holder d is formed so that the sole and heel pressing pads areseparated from each other by an intervening space ot" snliicient widthto receive a shank-presser, which is composed of a rigid holderf and apad or stripf aflixed thereto and formed to bear upon the shank portionof the sole. The shank-presser is supported by a rod or stern f2 thelower end of which is affixed to a block or head f3 to which theholderfof the shankpresser is connected by a segmental ribf4 tixed tosaid holder and entering a segmental groove formed in the head f3, saidrib and groove being arranged to permit the shankpresser to tip or rockerosswise ofthe sole. The shank-presser does not partake of theoscillating movements of the sole and heelpressing platen abovedescribed, but is adjustable vertically independently of said platen,soA that it can be depressed to any desired distance below the surfacesof the sole and heel pads, and thus act to confine the shank portion ofthe sole against the corresponding portion of the upper before the padsd2 and dis act on the fore-part and heel portions of the sole. Theshank-presser and its rod f2 are subjected to the downward pressure of aspringf5 which bears upon an adjusting nut f which is engaged with ascrew-thread on the upper portion of the rod f2, said spring beingsupported by a yoke or framef7 secured to a suitable support such as ahandwheel c3. The spring f5 holds the adjusting nut]c6 against asuitable support or bearing, which as here shown is the upper end ofthebushing e2 above described.

The adjusting nut uf has a hand-wheel]ES by which it may be rotated toraise or depress the rod f2 and the shank-presser. The shank-presser cantherefore be adjusted vertically independently of the sole and heelpressing platen, and is at all times yieldingly support-ed, the yieldingsupport being due to the spring f5 when the shank-presser is adjusted,so that its head j"3 is separated from the stop e. Vhen said head f3 isbrought in contact with the stop c bythe yielding of the spring f5, theshank-presser partakes with the sole-pressing platen of the yieldingmovement permitted by the spring c and the sliding coupling-member c.

It will be seen that the presser composed of the heel and fore-part padsaffixed to an oscillating holder common to them both, said holder havingalso a yielding `movement, and the shank-presser adjustableindependently of the heel and fore-part presser and having anindependent yielding movement as well as a yielding movement in commonwith that of the heel and fore-part presser, constitutes ICO TIO

a simple and eective means for co-operating with a jack in pressing asole against the lasted upper and maintaining the pressure while thecement is setting or hardening.

We do not limit ourselves to the details of construction abovedescribed, and may modify the same without departing from the spirit ofour invention.

In Fig. 9,/we show a modification in which the coupling-member on theholder d is a socket du, and the spring-pressed couplingmember is a balldw, the adjustable stop which limits the downward movementl caused bythe depressing spring d17 being a sleeve C118 having a flange at itslower end adapted to support the sliding part C119 on which the ball dlis formed. The sleeve du is adjusted by means of a nut d10 engaged witha screwthread on the exterior of said sleeve.

The jack comprises a base portion h having a telescopic standard hprovided with a toe-rest h2, and a slide h3 having a standard h4provided with a spindle h5 formed to enter the socket in the heelportion of the last, vthe slide h3 being adjustable by means of a screwh6. The jack is suitably engaged with a jackcarrier fi, which isvertically movable on the supporting frame, and is moved vertically toapply and remove pressure by means of a power mechanism which comprisestogglelinks j j connected respectively to the jackcarrier and to apower-driven gear-wheel k which rotates with the supporting-frame on thestandard a, and a cam m affixed to the standard a and formed to beengaged by an ove'rhanging trundle-roll t7'2 connected with the meetingends of the linksjj. The trundle-rollj2 is mounted on a frame orholderj3 which is connected with the linksjj and is provided with atrundle-roll j* bearing on the outer surface of the cam m, thetrundle-roll .i2 bearing on the inner surface of said cam.

The cam is formed to simultaneously hold the links'of all thetoggle-joints in alignment with each other, thus elevating thejack-carriers excepting at one point, where the meet ing ends of thelinks are thrown inward, thus depressing the jack-carrier and jack, asshown at the right in Fig. 1, so that the jack-carriers and jacks areelevated at all points excepting at one side of the machine, eachjack-carrier and jack being depressed when it reaches said point, whichis the operators station. vided with two cams n n aftixed to a rockshaftnjournaled in bearings in the jack-car- Eachjack-carrier is pro-` naryupward movement, so that the operators hands are left free to attend tothe other parts of the mechanism.

o represents a vertical rod located in the standard a and connected atits lower end to a treadle by the loperation of which the rod may bedepressed, the rod being normally raised by means of a spring o. On theupper end of the rod is formed an arm or hook o2 which is in position toengage a lug p' formed on a slide p2 which is movable in a slot p3formed in the tubular portion'b of the supporting frame. The slidep2 isconnected by means of a link p4 with an arm'ns affixed tothe rock-shaftn. When the jack is depressed and the cams heldy by the weight'of thejack in a depressed position, the slide p2 is elevated by the`connection betweenit and the cams, and is in position to engage thchook o2, so that when the `said hook is depressed by a movement of thetreadle, the rock-shaft 'n' and cams 'n will be turned to raise the jackindependently of the jack-carrier. A segmental ratchet q is affixed tothe jack-carrier in position to engage a springpawl q on the arm ns,said ratchet and pawl locking the cam inl its jack-raising position, asshown in Figs. 3 and 4.

1t will be understood that as the supporting frame rotates on thestandard a, the slide p2 connected with each jack carrier is raised whenthe jack-carrier is permitted to drop by the action of the cam mand thetoggle-links, as above described, so that said slide is in -position tobe engaged by the hook o2 and operated to raise the jack after theoperator has removed the completed shoe and applied an-A other to thejack. I.The operator is therefore enabled to change the position of thejack by foot-power.

The diagram shown in Fig. 7 shows the positions of the slide, cam, andvtreadle before the jack has been raised by the depression of thetreadle;and the diagram shown in Fig.v

8 shows the position of said parts after the jack has been raised by thedepression ofthe treadle. f
